[tcl_announce] ANNOUNCE: moodss-8.9
- Hi everybody: here is a new version of moodss.
Check it out! (or at least the screenshots at
Note: From now on, versions 10.x and above releases are for Tcl/Tk 8.3,
with corresponding releases using the 8.x version numbering for Tcl/Tk
8.0. Once Tcl/Tk 8.3 becomes part of the main Linux distributions,
development of the 8.x versions will stop.
Reminder: printing requires the dash patch (see moodss.htm file)
otherwise use moodss-10.1 along with Tcl/Tk 8.3 (see homepage)
### CHANGES ###
--- version 8.9 ---
in preferences dialog box, added canvas printing folder
added print preview using gv (ghostview)
in print dialog box, browse button did not work as it was invoking a
namespace procedure without namespace specification
added version, date and time to preferences save file
in configuration and preferences dialog boxes, use better looking
closed and opened folder icons
### README ###
This is moodss (Modular Object Oriented Dynamic SpreadSheet) version
8.9. Moodss is implemented in the great Tcl language (requires at
least versions 8.0 of Tcl and Tk, for UNIX or Windows).
Moodss won in the Best System Admin Technology category (Tcl Tips and
Tricks, Valuable Real World Programming Examples) at the O'Reilly
Tcl/Tk Conference on August 24, 1999.
Moodss is a modular application. It displays data described and
updated in one or more modules loaded when the application is
started. Data is originally displayed in tables. Graphical views
(graph, bar, 3D pie charts, ...), summary tables (with current,
average, minimum and maximum values) and free text viewers can be
created from any number of table cells, originating from any of the
A thorough and intuitive drag'n'drop scheme is used for most viewer
editing tasks: creation, modification, type mutation, destruction,
... Table rows can be sorted in increasing or decreasing order by
clicking on column titles. The current configuration (modules, tables
and viewers geometry, ...) can be saved in a file at any time, and
later reused through a command line switch, thus achieving a dashboard
The module code is the link between the moodss core and the data to be
displayed. All the specific code is kept in the module package. Since
module data access is entirely customizable (through C code, Tcl,
HTTP, ...) and since several modules can be loaded at once,
applications for moodss become limitless. For example, one can
compare a remote database server CPU load and a network load from a
probe on the same graph, or build a dashboard of CPU and memory
utilization for a group of servers.
Apart from a sample module with random data, ps, cpustats, memstats,
diskstats, mounts, route, arp, kernmods modules for Linux, ping for
UNIX, apache and apachex modules are included (running "wish moodss ps
cpustats memstats" mimics the "top" application with a graphic
edge). Module contibutions are of course welcomed and will be included
in my home page.
Thorough help is provided through menus, widget tips, a message area,
a module help window and a global help window with a complete HTML
Development of moodss is continuing and as more features are added in
future versions, backward module code compatibility will be maintained.
I cannot thank the authors of tkTable, BLT, wcb and the HTML library
enough for their great work.
In order to run moodss, you need to install the following packages
(unless you can use the rpm utility, see below):
obviously Tcl/Tk 8.0 or 8.2 at (or at a mirror near you)
http://www.scriptics.com/ or ftp://ftp.scriptics.com/
the latest tkTable widget library at:
and the latest BLT library at:
(see the INSTALL file for complete instructions, for UNIX and also
You also have the option of using the moodss rpm file (also in my
homepage), if you are using a Redhat Linux system (5.1 or above). The
required tcl, tk and blt rpms are part of the Redhat distribution,
whereas the tktable rpm can be found at:
Whether you like it (or hate it), please let me know. I would like to
hear about bugs and improvements you would like to see. I will correct
the bugs quickly, especially if you send me a test script (module code
with a data trace would be best).
you may find it now at my homepage:

Enjoy and please let me know what you think.
